Move ADISPLAY_ID_ definitions into LogicalDisplayId

These will eventually replace the existing definitions as follows:
     ADISPLAY_ID_NONE -->> LogicalDisplayId::INVALID
     ADISPLAY_ID_DEFAULT -->> LogicalDisplayId::DEFAULT

We are keeping the old definitions for now, to reduce the merge
conflicts. These will be removed in subsequent CLs, after the
frameworks/base and other repository patches go in.

The constant "NONE" was renamed to "INVALID" to make it consistent with
the Java definitions.
